A ELECTRIC SINGENG INSTEUM'ENT.

To all 'whom t may concern.' y

Be itl known that l, HARRY Y. Nonwoon, ot Rochester, in the county of Monroe 'and State of New York, have-invented certain new and useful improvements in Electric Singeing Instruments; and l do hereby declare the following 'to be a full, clear, and exactdescription of the same, reference being had to the accompanying drawings, forming a part. ci this specification, and to 'the refcrencenumerals marked thereon.

The present invention relates to electrically heated instruments, and it has for its particular object to providev a device of simple construction and capable of ready manipulation, the instrument being especially designed for use Where a co1npara tively high degree of heat is to be attained for singeing hair and similar purposes.

To these and other ends the invention consists in certain improvements and com binations ot1 parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the speciiication.

`ln the drawings; Figure l is a view in elevation ci? van instrument, connected for operation, and constructed in accordance with one embodiment of the invention;

Fig. 2 is a view in elevation, showing theA instrument in processor construction, and 3 is a longitudinal central section of 'the completed device.

Similar reference numerals throughout the several figures indicate the same parts.

The invention, as illustrated in the present embodiment, includes the body portion l, which is preferably constructed of a refractory insulating material, such, for eX- ample, as tire clay, and is .provided with a longitudinally extending central bore 2. The resistance element, as embodied in the present form' of the invention, is designated at 3, and comprises a Wire which ext/endsthroughthe longitudinal bore 2 of the body portion, and is connected at one end to the contact 4, the opposite end of the resistance Wire being extended beyond the end and around the outer surface ofthe body portion, to form the coil 5. The sleeve 6 is secured around one end of the body portion, and 'is connected with they resistance Wire by means ot a conductor 7 here shown as a fiat strip 7 extending longitudinally f the body portion and fitting closely against the surface thereof. The resistance.

coil 5 is lirst Wound about the body portion, as shown in Fig. 2, the conductor 7 being suitably conn ted to the-respective parts, and thereafter there is applied around the resistance coil and 'the adjacent end of the body portion, a cementitious ma terial 8, preferably lire ooit vand capable of withstanding a very h temperature Without cracking or separating. The cementitions covering serves to entirely inclosevthe resistance Wire and the end of the bedy pi rtion about ,which the Wire is coiled, and holds the latter 'i' ldly in its proper relaing strip 7, while anording at the saine time,

a comparatively large heat retaining sun face to ne applied to the hair, or other body to be heated or burned. The sleeve G is referabl* threaded the end of the bodv portion being correspondingly threaded to Vreceive the sleeve, which latter constitutes a plug to enable attachingthe instrumentto a. 'suitable socket, a circuit being completed through theh contacts e and t3.

In using the instrument, when current is applied, the resistance Wire becomes highly heated throughout, both interiorly and enteriorly of the body portion l, and the cement coveringis thus raised to the required .tem 'erature t r sin ein hair or such otherl purposes as may be desired.

" The instrument 1s always ready to-be instantly connected to an electric circuit, and the parts are heated suciently for opera' tion in a very few moments. The Contact carrying end of the body portion furnishes a convenient handle by Which the device may be held While in use. l

I claim as my invent-ion:

1. An electric instrument comprising a body portion ot refractorymaterial having a handle, a resistance element surrounding a the body portion,

contacts connected to the ends of the resistance element and a cementitious covering surrounding a portion of the resistance element, and forming the exterior' of the instrulnent.

3. An electric inetrument comprising a hollow body portion of refractory material having a handle a resistance element extending through the hollow body portion and surrounding a part ot the body portion, a conductor connected to one end of the resistance element, contacts connected respeo tively to the conductor and to the opposite end of the resistance element, and a ceinenti tious covering surrounding:r a portion of the resistance element, and forming the exterior of the instrument.

4. An electric instrument; comprising a hollow body portion of refractory material having a handle, a reeistance .element ezitending through the hollow body portion and extended around the outside ot' a part of the body portion, a flat conducting strip connected to one end of the resistance ele- 'ment and extendinglongitudinally ot' the HARRY Y.
